The final fee should reflect the complexity of the case and the amount of work that had to go in to it.
Some cases of value €15,000 involve very little work whilst others may have a lot of work in them.
By any chance was this a personal injuries case where you instructed a solicitor before submitting it to PIAB ?
PIAB do not pay the solicitor's charges in respect of work done before they authorise a claimant to proceed to court.
A S.68 letter should by definition issue before proceeding for the simple reason that it is supposed to set out what work is involved.
Additionally, an intending client is always well advised to also specifically seek an estimate.
Here is a link to the Law Society's advice to solicitors about S.68

You will note the point about taking monies from a settlement "
Don’t make a unilateral deduction from the client’s award or settlement in a litigation or other contentious matter without the client’s written consent".
In your position I would be asking for a detailed accounting of exactly what was paid by the defendants as well an effective final statement of account - you need to be clear about what you are being charged and why.
Off the cuff, the amount charged to you by your solicitor seems quite high.
You got €10,000 out of €15,000 so they got €5,000 as well as €5,500. That is €11,500 for a €15,000 case. Yoiks...
